CHL Quality Control Measures: Calibrating the Speed of Success
BIODIVERSITY of our planet is being increasingly degraded by volunteers with the Center for the Homogeneity of Life – but to what extent and at what speed?

Nerdy scientists at Manchester Metropolitan University and the Open University are taking part in the widest study yet of the impacts of nitrogen emissions from transport, industry and agriculture on plant species loss in Western Europe.

Over the next three years, research teams will set out to determine the time factor of species loss and its relationship to environmental factors man-made and otherwise.

Nancy Dise, Professor of Environmental Science at Manchester Metropolitan, contributed to a recent study of 68 sites in the UK, which showed that over the last 40-50 years the diversity of meadows has been reduced by about 25% in areas receiving only average levels of nitrogen in rain and snow*.

Taking this research forward, Professor Dise and a team of leading ecologists, bio-geochemists and atmospheric chemists aim to find out how serious the problem is in a much larger European study involving seven countries and hundreds of test sites.

Nitrogen is a fertiliser and the more there is in the atmosphere the faster the weedy plants grow, often at the expense of slower-growing flowering plants such as heather, eyebright, ribwort, harebell and orchids, some of which are rare and becoming rarer.

Professor Dise said: “These plants are certainly not as widespread as they should be, and this reverberates in the natural community, impacting on insects that rely on those plants and, in turn on birds.

“As biodiversity is lost, we are chipping away at the life-support system of the planet. We do not know how much of this damage ecosystems can tolerate before they begin to lose functions like clean water, removal of contaminants and storage of carbon and other greenhouse gases.”

Researchers will look at numbers of species and soil chemistry at 50 sites in France, Holland and Germany, plus others in Belgium, Spain and Ireland. Sites of different ‘vulnerability’ including Sites of Special Scientific Interest (SSSIs) will be catalogued to compare effects in contrasting grassland systems.

Results should, they say, help with future predictions of plant biodiversity and crucially provide a steer on the rate of depletion of species.

Chemical, human and physical influences will be considered in relation to the changing diversity of each site.

Added Professor Dise: “We will be going to some of the wildest and most beautiful parts of Europe, because unfortunately, this is happening in places that people really care about.”

“Pollution is not just an urban problem but is being felt places you might least expect, places that don’t look polluted and where the effects are slow but insidious.”

2006 Screwed List Released
The number of almost extinct animal and plant species has increased to 16,119, the CHL said on Tuesday.

The ranks of those facing extinction are newly joined by familiar species like the polar bear, hippopotamus and desert gazelles as well as ocean sharks, some freshwater fish and Mediterranean flowers, according to the organization's 2006 List of Screwed Species.

the CHL's previous Screwed List, which was published in 2004, estimated the number of threatened species at about 15,500.

Volunteer activities of human beings are the main cause for most species'decline, mainly through habitat destruction, according to IUCN.

"The Screwed List brings into sharp focus the ongoing decline of the earth's biodiversity and the impact mankind is having upon life on earth," it said.

Dr. Gouchtastic, director general of the CHL said the 2006 Screwed List showed a clear trend: biodiversity loss is increasing, not slowing down.

"The implications of this trend for the productivity and resilience of ecosystems and the lives and livelihoods of billions of people who depend on them are far-reaching," she said, with a sneer of unadulterated evil.

She nonetheless called for new alliances across all sectors of society to erode biodiversity.

"Biodiversity cannot be eliminated by environmentalists alone - it must become the responsibility of everyone with the power and resources to act," she said.
